• The gas-phase γ-radiolysis of a N<SUB>2</SUB>O-1-butene system has been reinvestigated. The other hydrocarbons used for the substrate are ethylene, propylene, 1,3-butadiene, cyclopropane, propane, and <I>n</I>-butane. The <I>G</I>-value of nitrogen from any system increased with an increase in the pressure of N<SUB>2</SUB>O and was saturated at about 4 mol% of N<SUB>2</SUB>O. The saturated value, <I>G</I>(N<SUB>2</SUB>)<SUB>max</SUB>, was much larger than the <I>G</I>-value of electrons estimated from the <I>W</I>-value of the hydrocarbon used and was rather strongly dependent upon the irradiation temperature, the dose rate, and the total dose. Some of the results were not consistent with those reported by the previous investigators. The reason for this discrepancy, and also the possible reaction mechanism to explain the large <I>G</I>(N<SUB>2</SUB>)<SUB>max</SUB>, have been discussed.
